WRENCH.

Specification of Letters Patent.

Patented Aug. 1, 1905.

Application filed December 19, 1904. Serial No. 237,502.

To a/ZZ whom it 71mg concern,.-

Be it known that I, JAMES H. SHEPHERD, a citizen of the United States, residing at Idaho Springs, in the county of Clear Creek and State of Colorado, have invented certain new and useful Improvements in Wrenches, of which the following is a specification.

My invention relates to new and useful improvements in wrenches, and more particularly to that class of wrenches wherein a sliding jaw is adjustable on the shank of the wrench.

The objects of my invention are to provide a wrench of this type which may be readily adjusted to any-sized nut, also to provide by my improved construction rapid means for manipulating the sliding jaw, and also to provide a wrench that can be uickly adjusted, though void of intercepted t eads and complicated parts necessary to the construction of that class of wrenches.

Further objects as to practicability and strength will be hereinafter fully explained.

My invention also consists in the construction, combination, and arrangement of parts hereinafter fully described, and specifically pointed out in the claim.

In describing my invention in detail I refer to the accompanying drawings, forming part of this application, and wherein like letters of reference indicate corresponding parts throughout the different figures, in which- Figure 1 is a side elevation of my new wrench. Fig. 2 is a longitudinal sectional view. Fig. 3 is a plan view of the sliding jaw. Fig. 4 is a view, partly sectional, of the knurled adjusting-nut. Fig. 5 is a plan view of the sleeve or collar. Fig. 6 is a cross-section along line a a of Fig. 2.

In more fully referring to the drawings, A re resents the shank of the wrench, preferab y constructed in oblong shape, as will be made manifest by consulting Fig. 6. It is provided with a fixed jaw A. The shank A is provided with apertures toward the lower extremity, (designated by A2 and A3,) to which reference will be hereinafter made.

B represents the sliding jaw adapted to be mounted on the shank A, as illustrated, it being provided with an oblong aperture adapted to encircle the shank. The sliding jaw B has a downward extending boss or sleeve, (designated by B,) which is circular and provided with external threads B2.

` C designates a sleeve having an oblong aperture extending through its longitudinal length adapted to iit over the shank, as illustrated in Fig. 2. It is provided with a collar or reinforcement O, designed to operate as a ferrule. The upper part C2 of the said sleeve O is provided with external threads C3, which will be hereinafter more fully referred to. An aperture C4 is provided in the sleeve O near its lower extremity adapted to receive a pin, which also asses through the aperture A3 in the shank by means of which the sleeve is rigidly secured to the shank.

D represents the knurled adjusting-nut, which is provided with internal threads divided equally D and D2, one portion being right-hand threads and the other portion lefthand threads, as will be made manifest in Fig. 4 of the drawings. It will be observed that the length of the knurled nut is substantially equal to the combined length of the sleeve B and the threaded part O2 of the sleeve C.

E represents the handle, which may be constructed of wood, metal, or any suitable material. It is secured to the shank A by means of the screw E', operating in the internallythreaded aperture A2, provided in the shank A. -The handle is of ordinary construction.

It will be made manifest by consulting Figs. l, 3, 4, and 5 of the drawings that the right-hand and left-hand threads are of the same pitch or angle, thereby equalizing the lift or movement of the different parts and minimizing the friction. This will be found to be an essential feature and specifically a part of my new wrench.

It is obvious that the operation of my new wrench is simple and practically the same as the old-style wrench, inasmuch as it has no complication of parts and no intricacies to get out of order. It is fully as strong and durable as the old-style wrench so steadfastly adhered to by most mechanics and shop men. The improvement over the said old-style wrench is comprehensible, in that one rotation of the knurled nut D moves the jaw B twice as far in either direction as a single rotation of the knurled nut or similar contrivance for revolving the adjusting stem or spindle would move the jaw of the oldstyle Wrench. The sleeve extending into the handle keeps the shank from contact with the handle, so as not to wear the socket therein, and by the disposition of the parts, as shown, the shank is inclosed and surrounded throughout practically its entire length and being secured to the portion of the sleeve within the handle and by independent means to the handle maximum rigidity and iirmness is obtained.

What I claim, and desire to secure by Letters Patent, is-

As an improved article of' manufacture the herein-described Wrench consisting of the fixed jaw With shank oval in cross-section and having a plurality of apertures near the end farthest from the avv, a sleeve having central enlargement C with shoulders, the portion upon one side of said enlargement embracing the said shank, means passed through the same and through one of the openings of the shank, a handle having a shouldered bore receiving said portion and abutting vagainst one of the shoulders thereof, means passed JAMES H. SHEPHERD.
